A Study on How Climate Change Affects South Asia

South Asia is vulnerable and most affected by adverse impacts of climate change. The study examines the impact of climate change on South Asia during the past years and predict future, resulting in unprecedented heat waves and drought in summers followed by abnormal rains and floods during the monsoon season. Agriculture is the backbone of South Asia’s economy, which has been devastated by both drought and floods. This research argues that water security is an emerging national security challenge for South Asia. The article investigates the status of water availability with relation to the burgeoning population, agriculture, and other uses of water. The impact of abnormal melting of glaciers, the no availability of dams for storage of rainwater, and lack of smart means for agricultural water have been examined to empirically validate the arguments.
